Bugatti Chiron shatters speed record at more than 300 miles per hour

Bugatti just won the race to 300 mph with a Chiron

The 8.0-litre, W16 quad-turbo engine itself has been upgraded from the standard 1,479bhp to 1,578bhp but still drives the vehicle through the production version's seven-speed gearbox and four-wheel-drive system.

With British racing legend Andy Wallace at the wheel, a tuned Chiron Sport hit a top speed of 304.77mph (490.47 km/h) at a test track in Germany, beating the previous record by nearly 27mph. The tail cross-section is small to improve stability and the active rear wing-cum-brake has been ditched in favour of a fixed unit to reduce drag and save weight. It's incredibly hard to make ones that can handle the rotational velocities seen at speeds higher than that, and the Chirons already cost over $30,000 per set and need to be replaced every 2,500 miles. That speed sets a new world speed record for a production vehicle.

The new benchmark shatters the 431km/h top speed of the previous-generation Bugatti Veyron. Meanwhile, the all-wheel-drive system and the seven-speed dual-clutch transmission were also retuned to handle the additional power.

Bugatti spent around six months to prepare the auto for the high-speed run, and worked directly with Michelin to come up with some tyres that could handle such insane speeds.

Inside, the high-speed Chiron has been stripped of a passenger seat, replaced with myriad computer systems. A bucket seat and full roll cage were also installed to keep the driver safe. Our goal was to be the first manufacturer ever to reach the magic 300mph mark.

Stephan Winkelmann, president of Bugatti, said: "What a record!"

"We have shown several times that we build the fastest cars in the world".

Whereas a lot of manufacturers - together with Hennessey, SSC and Koenigsegg themselves - had beforehand claimed their newest machines are able to breaching 300mph, the prototype Chiron - a modified model of the £2.5million hypercar - is the primary to register the landmark velocity formally. A feat that's certainly impossible on humdrum traffic congested real-world roads, but achievable on a strip long enough to realize the potential of these beasts, like Bugatti did recently, with its modified Chiron in Germany.
